Description
技术领域technical field
本实用新型涉及矿用设备，尤其涉及一种深孔注水封孔器。The utility model relates to mining equipment, in particular to a deep hole water injection sealing device.
背景技术Background technique
我国瓦斯喷出、煤与瓦斯突出、瓦斯爆炸等事故时有发生。煤层注水、松动爆破、煤层水力压裂等技术是防治瓦斯灾害的有效手段。有效封孔是实现高效注水、安全松动爆破和高效水力压裂的首要条件。常规的钻孔封孔方法除了采用水泥砂浆、黄泥等封孔外，也可以采用胶管封孔器封孔。常规的煤层注水胶管封孔器分为两种：一种是在胶管内部安设有承压单向阀来实现煤层注水，这受到煤层注水压力的限制，胶管内部的压力一般不高，此外承压单向阀精度不理想，这都导致封孔效果不理想。特别是将胶管用于封堵爆破孔的过程中，如果胶管内部压力不够，很容易导致胶管在放炮瞬间被抛出。另一种是在胶管的一端安设有密封滑道，以适应胶管在注水膨胀后引起长度收缩，避免胶管被内部的管路撑坏。由于密封滑道的密封效果不理想，高压时候容易漏水，且容易损坏；此外由于胶管内部的管路一般是硬质管路，收缩性差，当密封滑道损坏后，很容易导致胶管在注水过程中损坏。Accidents such as gas ejection, coal and gas outburst, and gas explosion occur from time to time in our country. Coal seam water injection, loose blasting, coal seam hydraulic fracturing and other technologies are effective means to prevent and control gas disasters. Effective hole sealing is the primary condition for efficient water injection, safe loose blasting and efficient hydraulic fracturing. In addition to using cement mortar, yellow mud, etc. to seal holes in conventional drilling and sealing methods, rubber hose sealers can also be used to seal holes. Conventional coal seam water injection hose sealers are divided into two types: one is to install a pressure-bearing one-way valve inside the hose to realize coal seam water injection, which is limited by the pressure of coal seam water injection, and the pressure inside the hose is generally not high. The accuracy of the pressure check valve is not ideal, which leads to the unsatisfactory sealing effect. Especially in the process of using the rubber hose to seal the blast hole, if the internal pressure of the rubber hose is not enough, it is easy to cause the rubber hose to be thrown out at the moment of blasting. The other is to install a sealing slideway at one end of the rubber hose to adapt to the length contraction of the rubber hose after it expands with water, so as to prevent the rubber hose from being damaged by the internal pipeline. Due to the unsatisfactory sealing effect of the sealing slideway, it is easy to leak and damage under high pressure; in addition, because the pipeline inside the rubber hose is generally a hard pipeline with poor shrinkage, when the sealing slideway is damaged, it is easy to cause the hose to be damaged during the water injection process. damaged.

实施例Example
如图1和图2所示，一种深孔注水封孔器，包括外胶管1、钻孔注水管4和胶囊注水管10。外胶管1在内部承压时可以膨胀，外胶管1的两端分别固定在胶囊堵头(2、3)上，外胶管1与两端的胶囊堵头(2、3)构成封闭腔体。钻孔注水管4的两端分别穿过两个胶囊堵头(2、3)并分别固定在两个胶囊堵头(2、3)上。钻孔注水管1位于封闭腔体内的部分有一段为可伸缩的软管5，钻孔注水管4两端靠近两个胶囊堵头(2、3)的部分为硬质管(6、7)，胶囊注水管10位于其中一个胶囊堵头上，胶囊注水管10的一端伸入封闭腔体内。胶管堵头(2、3)和硬质管(6、7)可以为钢铁、不锈钢、铝合金等金属材料也可以为硬质塑料。As shown in FIG. 1 and FIG. 2 , a deep hole water injection sealing device includes an outer rubber tube 1 , a drilling water injection tube 4 and a capsule water injection tube 10 . The outer rubber tube 1 can expand when it is under pressure inside, and the two ends of the outer rubber tube 1 are respectively fixed on the capsule plugs (2, 3), and the outer rubber tube 1 and the capsule plugs (2, 3) at both ends form a closed cavity. The two ends of the drilling water injection pipe 4 respectively pass through the two capsule plugs (2, 3) and are respectively fixed on the two capsule plugs (2, 3). The part of the drilled water injection pipe 1 located in the closed cavity is a flexible hose 5, and the parts of the drilled water injection pipe 4 near the two capsule plugs (2, 3) are hard tubes (6, 7). The capsule water injection pipe 10 is located on one of the capsule plugs, and one end of the capsule water injection pipe 10 extends into the closed cavity. Rubber hose plugs (2,3) and hard tubes (6,7) can be metal materials such as steel, stainless steel, aluminum alloy and can also be hard plastics.
装配时，将钻孔注水管4从外胶管1的内部穿过，钻孔注水管4两端的硬质管(6、7)分别穿过胶管堵头(2、3)，软管5位于外胶管1的内部，再将硬质管(6、7)和胶管堵头(2、3)分别焊接，焊接处8和焊接处9在保障密封效果的情况下可使整个封孔器具有非常好的密封性能。常规的类似封孔器设计过程中，其内部一般都采用硬质的金属管路，由于封孔器内部注水膨胀时，其长度会收缩，因此内部金属管必须也能收缩，这一般是通过串联一个伸缩滑道来实现，而伸缩滑道一般设置在胶管堵头位置处，内部管仅仅一端是和胶管堵头焊接在一起，另一端是密封滑动的。滑道处需要密封连接，保障在高压注水的时候不会发生漏水，长时间使用时滑道很容易损坏，从而导致整个封孔器损坏。本实用新型的一种深孔注水封孔器其内部为软管5，能随着封孔器的伸缩而变形，因此其内部不需要安装滑道，钻孔注水管4的两端和外胶管1两端的胶管堵头(2、3)直接焊接，加工方便并减少了漏水点，大大提高了密封效果，非常适用于爆破钻孔和注水钻孔的封孔作业。此外，软管5重量较轻，也大大降低封孔器的整体重量。When assembling, pass the drilled water injection pipe 4 through the inside of the outer rubber hose 1, the hard tubes (6, 7) at both ends of the drilled water injection pipe 4 respectively pass through the rubber hose plugs (2, 3), and the hose 5 is located on the outer Inside the rubber hose 1, the hard tubes (6, 7) and the rubber hose plugs (2, 3) are welded respectively. The welds 8 and 9 can make the whole hole sealer have a very good sealing effect while ensuring the sealing effect. sealing performance. In the design process of conventional similar hole sealers, hard metal pipes are generally used inside. Since the length of the hole sealer will shrink when the inside of the hole sealer expands with water injection, the internal metal pipe must also be able to shrink. This is generally done through series connection. It is realized by a telescopic slideway, and the telescopic slideway is generally set at the position of the hose plug, only one end of the inner tube is welded with the hose plug, and the other end is sealed and slid. The slideway needs to be sealed and connected to ensure that there will be no water leakage during high-pressure water injection. The slideway is easily damaged when used for a long time, which will cause damage to the entire hole sealer. A kind of deep hole water injection sealing device of the utility model has a hose 5 inside, which can be deformed with the expansion and contraction of the sealing device, so there is no need to install a slideway inside, and the two ends of the drilling water injection pipe 4 and the outer rubber tube 1. The rubber hose plugs (2, 3) at both ends are directly welded, which is convenient to process and reduces water leakage points, greatly improving the sealing effect. It is very suitable for the sealing operation of blasting drilling and water injection drilling. In addition, the hose 5 is light in weight, which greatly reduces the overall weight of the hole sealer.
